Environmental Conditions Drive Demand for Four-Track Tractor
It’s no secret spring 2015 was abnormally wet, which led to unfavorable planting conditions across portions of the Midwest. With tight margins and ever-changing weather and environmental conditions, articulated track solutions are in high demand to counteract variable field conditions. To meet this need, John Deere expands its lineup to include its first four-track tractor offering, the 9RX Series.
“We continued to watch the strong presence of two-track tractors across the countryside and anticipated four-track tractors to be our next step,” says Colin MacDonald, product manager, 9 Family Tractors. “The time was right and demand was there, so we went for it.”
This 9RX four-track series broadens the fleet of 9R/9RT wheel and two-track tractors and sports the same features and options. The series features four models: 9470RX, 9520RX, 9570RX and 9620RX.
The 9570RX and 9620RX are powered by a 15-liter Cummins QSX15 engine, and the other two tractors are equipped with a PowerTech PSS 13.5-liter engine. All engines are Tier 4 Final-compliant.
With a sealed cartridge mid-roller design, the undercarriage system sports a large diameter 39.5" drive sprocket. This system also has two large diameter mid-rollers, instead of three, which are spaced on the side of the axle. This improves ride quality and reduces wear for increased mid-roller life.
“The idea behind the 20% larger diameter is to slow down everything,” MacDonald says. “Now you can travel the same speed, dissipate heat more effectively and run the entire undercarriage more efficiently.”
Built from experience, the four-track models feature the Camoplast Duradrive 3500 and 6500 Series tracks with positive drive versions. The drive lugs mesh with the drive sprocket to effectively transfer the power through the tracks in high horsepower, high torque applications. The tracks engage six drive lugs into the drive sprocket for better performance. The 9RX wide belt tractor undercarriages are fixed at 87" from center belt to center belt and are available in 30" and 36" widths.
Moving from the exterior to the inside of the cab, the 9RX Series features a cab suspension system on all four corners. A parallel plane four-bar linkage controls movement and helps decrease in-cab impact and vibrations. The cab spans plus or minus 2" of vertical travel from the center.
Similar to the 9R/9RT features, the 9RX Series includes CommandView III cab, Generation 4 CommandCenter, integrated FarmSight technologies and e18 Transmission with Efficiency Manager. Active Command Steering, 115 gal. of flow and up to eight rear selective control valves are optional.
Despite lower commodity prices, John Deere anticipates demand to be exceptionally strong for the 9RX
four-track solution to help farmers address tough field conditions, MacDonald says.
